Abstract

В заявке описаны способ и устройство для очистки от твердых частиц полимера трубы, которая соединена с циркуляционным реактором. Устройство имеет датчик (441) давления в циркуляционном реакторе (1), установленный на идущем к нему трубопроводе, сообщаемый с ним первый клапан, второй клапан (418), расположенный между трубопроводом (416) и первым источником (412) инертного разбавителя и сообщаемый с трубопроводом (416) в точке, расположенной между циркуляционным реактором (1) и первым клапаном. По сигналу датчика (441) первый клапан закрывается, а второй открывается, обеспечивая поступление в трубу инертного разбавителя в необходимом для ее очистке от твердых частиц полимера количестве и достаточном давлении.Отчет о международном поиске был опубликован 2000.08.31.The application describes a method and apparatus for cleaning solid particles from a polymer pipe that is connected to a circulation reactor. The device has a pressure sensor (441) in the circulation reactor (1) installed on the pipeline coming to it, the first valve communicating with it, the second valve (418) located between the pipeline (416) and the first inert diluent source (412) and communicated with pipeline (416) at the point located between the circulation reactor (1) and the first valve. At the signal of the sensor (441), the first valve closes and the second opens, ensuring that an inert diluent flows into the pipe in the quantity and sufficient pressure necessary for cleaning it from solid polymer particles. An international search report was published on 2000.08.31.
